381232 ÷ 42 
The aim is to understand the frequency of 42 in 381232.

Let's proceed to step 1:
The number 42 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 42

Step 2:
If we divide 38 by 42, we get 0 and a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 42

Going ahead to step 3:
If we divide 381 by 42, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 378 from 381 leaves us with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 42

Advancing to step 4:
When dividing 32 by 42, we get 0 with a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Deduct 0 from 32 and we're left with 32.
Take the next digit (3) from the dividend and append it to 32, then repeat: 323 / 42

Step 5:
42 can be fit into 323 7 times, resulting in a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 907.0
If we subtract 294 from 323, we get 29.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 42

Let's proceed to step 6:
292 divided by 42 is 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 9076.0
Subtracting 252 from 292 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
42 goes into 400 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 9076.9
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
220 divided by 42 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 9076.95
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
42 can be fit into 100 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 9076.952
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
If we divide 160 by 42, we get 3 and a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 9076.9523
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
If we divide 340 by 42, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 9076.95238
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
42 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 9076.95238
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 9076.9523809
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
42 goes into 220 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 9076.95238095
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 9076.95238095 with a remainder of 1e-08.
